A content delivery network (CDN) is a system of distributed network that builds with servers and delivers web pages, other web content to a user, based on the geographic locations of the user. On the other hand, Content delivery networks are the transparent backbone of the Internet in charge of content delivery.
Content Delivery Network or CDN use multiple servers in many geographic locations that improve deliveries of static and streaming content. Global content requests automatically get routed to the closest servers, speeding up page loads, maximizing bandwidth and providing identical content regardless of Internet- or site-traffic spikes. Depending on traffic and number of nodes, the network’s algorithms select the best routing options to deliver optimum performance and avoid bottlenecks.
Users with high-speed connections often experience choppiness, loading lags and poor quality, especially when viewing live events or if they are located far from the hosting servers. CDNs minimize latency issues that cause image jitters, optimize delivery speeds and maximize available bandwidth for each viewer.
How Content Delivery Network (CDN) Work
Servers nearest to the website visitor respond to the request. The content delivery network copies the pages of a website to a network of servers that are dispersed at geographically different locations, caching the contents of the page. When a user requests a web page that is part of a content delivery network, the CDN will redirect the request from the originating site’s server to a server in the CDN that is closest to the user and deliver the cached content. CDNs will also communicate with the originating server to deliver any content that has not been previously cached. The process of bouncing through CDNs is nearly transparent to the user. The only way a user would know if a CDN has been accessed is if the delivered URL is different than the URL that has been requested.
Benefits of CDNs
Business owners face increasing storage needs for all kinds of content, but they must deliver these materials quickly. CDNs facilitate faster page loads and offer other important benefits including the following advantages:
Eliminate Pauses and Accommodate Heavy Traffic
Video streaming often results in jitters and pauses due to lags in transmission times, but CDNs help to deliver better user experiences when downloading video and audio content.
Minimize Packet Loss
Users get improved streaming quality.
Faster Loading
Internet speeds improve, but people expect nearly instantaneous page loads. Faster load times increase sales according to many studies and a vast body of anecdotal evidence.
File Mirroring
File mirroring protects data if natural disasters affect certain areas of the Internet. Hurricanes and earthquakes could cause significant disruptions to services in key geographical areas.
Optimize Live Delivery
The success of YouTube and social media sharing has made video extremely popular, and most businesses should consider adding video elements to their content.
- Live events help to generate increased traffic.
- Small organizations and schools can broadcast live events to strengthen SEO efforts.
- Anyone can broadcast live networks of material as part of a marketing strategy.
Enable Linear Networks - Companies can broadcast in the same way that major networks do, creating their own program schedules for 24-hour CDN deliveries around the world.
Support Video on Demand
Organizations can enhance their online presence with video libraries, how-to videos, training programs, and other marketing tools.
Scalability
New technology and advanced mobile applications place increasingly greater demands on servers, but large CDNs can handle new material as companies expand their online presences.
